摘要 为快速估算出垂直极化平行板有界波电磁脉冲(EMP)模拟器的时域近场,将散射传递函数法应用于该类型模拟器近场的时域计算中,即对于给定的脉冲源,先寻找有效频谱范围能覆盖该源的高斯脉冲源,并应用时域有限差分(FDTD)方法计算该高斯脉冲源激励时模拟器中测试点场的时域响应,再利用傅里叶变换、系统的传递函数及傅里叶逆变换计算得到给定脉冲源激励时各测试点场的瞬态响应。所得计算结果与直接使用给定脉冲源激励时FDTD方法的计算结果符合较好。所述方法可用于同一模拟器在不同脉冲源激励时辐射近场的快速估算,能大大减少FDTD模拟计算的次数,尤其对于中大型模拟器能有效减少计算时间和内存。 For fast estimating the time-domain near-fields of flat-plate bounded wave electromagnetic pulse(EMP) simulator with vertical polarization,scattering transfer function method is used in time-domain simulation of this kind of simulator.A Gaussian pulse,whose effective frequency domain is wider than that of a given pulse source,is found firstly.And the time-domain response of electric fields at some testing points in the simulator excited by the Gaussian pulse source can be got by finitedifference time-domain (FDTD) method.Then the transient response of electric field at each testing point as the simulator excited by the given pulse source can be computed by Fourier transform,system transfer function and inverse Fourier transform.The results are well consistent with those got by FDTD method as the simulator is excited by the given pulse source directly.The method in this paper is useful for fast estimating radiation near-fields of a fixed simulator with different exciting sources.It has the advantages of reducing FDTD simulation time,saving much computing time and CPU storage especially for medium or large simulators.
